Installation Notes

  1. Ensure the engine is off and cool. Place a suitable container below the filter housing to catch any spilled oil.
  2. Carefully unscrew the oil filter housing cap or center bolt.
  3. Remove the old filter element and any associated gaskets or O-rings.
  4. Clean the inside of the filter housing and the cap threads, removing any old sludge or debris.
  5. Lightly lubricate the new O-rings/gaskets with fresh engine oil before installing them onto the housing or cap.
  6. Insert the new oil filter element into the housing, ensuring it is seated correctly.
  7. Re-install the housing cap and tighten it to the torque specified in your engine's service manual. Do not overtighten.
  8. After installation, run the engine for a few minutes and carefully check for any leaks around the filter housing.
  9. Switch off the engine, then re-check the oil level and top up as necessary.

Troubleshooting & FAQ

How do I know if this filter fits my engine?

This kit is designed for Yanmar 6HA, 6HAL, and 6HAK series engines. Please check the "Engine & Model Compatibility" table to confirm your engine model is listed. For 100% certainty, always compare the part number 126650-35350 against the number specified in your engine's service manual before purchasing.

What is the difference between this element and the original Yanmar filter?

This is an aftermarket replacement part built to meet or exceed OEM specifications for fit, function, and filtration efficiency. It offers a reliable and cost-effective alternative to the genuine Yanmar part without sacrificing quality or performance.

How often should I replace this oil filter element?

The replacement interval should align with the schedule recommended in your Yanmar engine's service manual. Oil filter elements are typically changed along with the engine oil, usually based on service hours or at least annually, whichever comes first.

What are the signs of a clogged or failing oil filter?

A severely clogged filter can lead to a drop in oil pressure (triggering a warning light), reduced engine performance, or an increase in engine operating temperature. However, it is best to replace the filter at regular service intervals to prevent these issues from occurring and avoid potential engine damage.
